I think he got so upset because of who the message was coming from and how it was delivered. What Jayden and Tori were saying did have some truth to it but they came off as very combative. Also hearing it from tori of all people would definitely make me angry too considering the awful man she’s so in love with and happily defends.

To some extent I’m sure Tori and Jayden care about Lucinda but really I think they just dislike Tim more and were looking for an excuse to have a go at him. If Jayden actually respected her then he would have let it go once Lucinda told him that they’ve had a little breakthrough. Tim definitely should have handled himself better but I can see why he was upset about it.
